'campaigned' is the definition.
Both the answer and definition are past participle verbs.
Perhaps they are linked in a way I don't understand?

'lee into decree broadcast' is the wordplay.
'broadcast' indicates an anagram (letters scattered or cast around).
'lee'+'into'+'decree'='leeintodecree'
'leeintodecree' with letters rearranged gives 'ELECTIONEERED'.

'to get' acts as a link.

Can you help me to learn more?

(Another definition for electioneered that I've seen is " Canvassed".)
